I use Smart Cat which is wood pellets and great and know they do a paper one, but was a bit dubious to try it.
How much of it do you use compared to wood pellets?
I don't know, I used the wood pellets once and they were like ' I'm sorry but what is THAT '.
Last week I put normal in half their trays and the paper pellets in the other, fully expecting the paper pellets tray to remain unused or just batted about. I was pleasantly surprised. I think I'm going to be using more than their normal litter tho.
My cats are weird tho, they hate any form of clumping litter, so this is great for them, but I imagine crap for others.
How awful for your cat puffball.
